Technical Note: Grating Selection for Raman Spectroscopy

What is the best grating for your Raman spectrometer? Read this technical note to find out! The application team investigates a range of excitation wavelengths, and 5 different gratings to provide an insight into grating selection.

Technical Note: Choosing Laser and LED Sources for Time-Resolved Photoluminescence Experiments

As photoluminescence (PL) research evolves, so does the demand for sensitive instrumentation to measure increasingly weak PL signals. Besides photon-counting detectors and monochromators with good stray light rejection, the source used to excite the sample is a key component to consider when designing an experiment.

Technical Note: Measuring Fluorescence and Phosphorescence Spectra at Low Temperature Using the FLS1000 Photoluminescence Spectrometer

In this technical note, an Edinburgh Instruments FLS1000 Photoluminescence Spectrometer was used to acquire the fluorescence and phosphorescence spectra of a fluorescent emitter at 100 K.

Technical Note: Avoiding Dead Time Losses with Reverse Mode TCSPC in the FLS1000

Time-correlated single photon counting (TCSPC) is the method of choice for measuring fluorescence lifetimes due to its excellent time-resolution. TCSPC can be thought of as a very fast stopwatch with two inputs (Figure 1)...

Technical Note: LP980 Transient Absorption Spectrometer Diffuse Reflection Accessory; Alignment and Example Measurements of Benzil Powder

This Technical Note is written to show customers how to properly align and measure solid samples using the LP980 Transient Absorption Spectrometer when equipped with the diffuse reflection accessory.

Technical Note: Benefits of Using a Gated PMT Detector in the FLS1000

The photomultiplier tube (PMT) is the detector of choice for high performance fluorescence spectrometers such as the Edinburgh Instruments FLS1000, due to its excellent light sensitivity and ability to be used for both steady-state and time-resolved measurements...

Technical Note: LP980 Transient Absorption Spectrometer Beam Alignment - Optimising Signal for the Highest Sensitivity Measurements

In this technical note we explore Transient absorption (flash photolysis), which is a powerful tool to understand many photochemical properties and reactions, from measuring the energy levels and lifetimes of excited singlet and triplet states, to measuring electron and energy transfer rates of paired molecular systems, and even photocatalysis intermediates and products.

Technical Note: Automation of Photoluminescence Measurements using Batch Mode Scripting

In this technical note we describe the operation of Batch Mode and demonstrate two examples where it is useful: temperature maps of anisotropy and measurements on multiple samples.

Technical Note: Polarised Raman Spectroscopy

This technical note will introduce some basic theory about polarisation of light and polarised Raman spectroscopy, before demonstrating different types of samples the RM5 can analyse using this technique.
